You whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion. Which of the following is t

rue for this situation? (Select all that apply.)
a. The direction of the stone's velocity changes as it moves around the circle.
b. The magnitude of the stone's velocity does not change.
c. The stone's speed is constant.
d. The change in direction of the stone's motion is due to the centripetal force acting on the stone.
e. The stone is moving with constant velocity.

a. The direction of the stone's velocity changes as it moves around the circle.

b. The magnitude of the stone's velocity does not change.

d. The change in direction of the stone's motion is due to the centripetal force acting on the stone.

Above given are true for the given situation.

<u>Answer:</u> Option A, B and D

<u>Explanation:</u>

Circular motion may be characterized as the moving of an objects along the diameter of the circle or any circular direction. It may be standardized and non-uniform based on whether or not the rate of rotation is unchanged.

The velocity, a vector quantity is constant in a uniform circle motion speed is constant as its direction continues to change. Centripetal force works inward toward the core to counterbalance the centrifugal force from the center moving outward.

A box of mass 1 kg is hung from a spring scale. The reading on the spring scale is approximately 10N. What would be the reading
8090 [49]
The answer will be 50N.
This is because the spring reads weight and weight is mass times acceleration due to gravity.5kg*10m/s2=50N

A block oscillating on a spring has period T = 2.8 s . (Note: You do not know values for either m or k. Do not assume any partic
olasank [31]

Answer:

Part a)

T = 3.96 s

Part b)

T = 1.98 s

Part c)

T = 2.8 s

Explanation:

As we know that time period of spring block system is given as

T = 2\pi\sqrt{\frac{m}{k}}

T = 2.8 s

Part a)

If the mass of the block attached is doubled

then we will have

T' = 2\pi\sqrt{\frac{2m}{k}}

T' = \sqrt2 T

T' = 3.96 s

Part b)

If the spring constant is doubled

then we have

T' = 2\pi\sqrt{\frac{m}{2k}}

T' = \frac{T}{\sqrt2}

T' = 1.98 s

Part c)

If the amplitude is halved but mass and spring constant will remain the same

so here we know that time period does not depends on Amplitude

so we will have

T = 2\pi\sqrt{\frac{m}{k}}

T = 2.8 s
